METHOD OF SYNCHRONISING NODES OF A NETWORK, AND SYSTEM AND DEVICE THEREFOR

摘要

A method of and a system for synchronising a plurality of spaced apart nodes of a network to a reference time of a control centre, the method comprising receiving measurement data from each of the plurality of nodes; ranking the plurality of nodes with respect to one another according to the measurement data; selecting one or more master nodes from the plurality of nodes according to the ranking; assigning each of the plurality of nodes to a corresponding master node; determining a first time offset between the local time measured at each node and the local time measured at its corresponding master node and determining a second time offset between each of the master nodes and the reference time such that the time offset between the local time measured at each node and the reference time can be determined.
